Thanks, I'm sorry I did not looked harder before asking. But this does 
not rule out using <figure role="img">. Firstly, quoting ARIA, 
role="img" designate a group *as well*:

]]
group
   	A set of user interface objects which are not intended be included 
in a page summary or table of contents by assistive technologies.
  []
img
	A container for a collection of elements that form an image.
[[

Secondly, an img doesn't take part in in the TOC.
